FLAME SPREADER.

Application filed October 7, 1921.

To all whom it may concern:

Be it known that I, EDWARD F. DRAKE, a citizen of the United States, residing at Danbury', in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Flame Spreaders; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of the specification.

My invention relates to a flame spreader or baffle-plate for enlarging thefiame of an oil burner, for lamps or stoves adapted to be attached to the ordinary burner.

I find in practice that the flame spreads out and increases in width as well as being enlarged by the updraft of air between my device and the conventional form of hood or bell to which it is attached. The air enter ing through the lower slots of my device and passing out through the holes near the top thereof. The holes being on opposite sides of the wick. The projections formed in making the holes keep my device at a predetermined distance from the hood thus I am able to provide the same air space on each side of the wick causing thereby an even flame. My device also makes asteady flame which is of great advantage to readers. It will be seen from the foregoing that I add air to my flame causing thereby a better vaporization.

I have found it desirable to use white metal as this produces a white mellow light- Referring to the drawings :--Fig. 1 is a plan View of a conventional burner showing my device partly in full and partly in dotted lines. Fig. 2 is a vertical cross section taken on the line 2-2 of Fig. 1. Fig. 3 shows a plan View and Fig. 4 a side view of my device.

Referring more particularly to the draw- Specification of Letters Patent.

ings:-1O designates a burner of the ordt nary construction. 11 denotes the conventional form of dome hood or bell. 12 shows location of the slot in the dome. 18 the wick tube, 1% denotes the usual base of a burner. 15 denotes ears which are bent to hold my device 16 against the dome l1, lips 17 are provlded to keep my device at a predetermined distance from the side of the dome to allow an air space, an upward draft enters between the dome and my device, through slots 18 provided at the bottom thereof, near the top and immediately below the lips 17 are formed holes 19 through which the updraft exits. It will be noted that these holes 19 allow air to exit on either side of the edge of the wick, not shown, thus raising,

and spreading and causing a better combustion and a more efficient light. i

It will be seen that the baffle plates 16' are bowed lengthwise as shown in Fig. 4: and when in position air is admitted at each side as shown in Fig. 5. Thus by my constructionair is admitted on each side of the bafile plate as well as from below through slots 18, and is directed to exits 19 so positioned that air is supplied at the edges of the wick on each side of said edges.

My baffle plates are readily applied to burners in use, no tools being required, as the ears are readily bent over the edges of the dome slot and under the dome base by hand.

I clai.m

The combination with an oil burner dome, of balile plates having ears adapted for bendable engagement with the ends of the dome slot and the dome base,said plates being bowed lengthwise, their lower edges slotted, their upper portion perforated at each side and provided with bearing lips.

In testimony that I claim the foregoing as my own, I aflix my signature.
